The consensus on the AM thread is to not use the blue and breed the splash for a replacement blue for next year. That means it will be at least a year before I possibly have a good black breeding cockerel, but at least I would know I'm not breeding the leakage forward. I'm thinking move all the hens to Jack, sell Johnny, and put the new BCM in that pen for now. They are ready to move outside
Sounds like a good plan, sorry it slows down your original plan, but you'll still have some great ones to work with until then.
